Many people I speak with who have taken calculus remember vaguely some of the techniques they learned but say they never really understood what calculus was all about. The videos in this section are aimed at these people. We focus on the big ideas behind calculus so that you can see the reasons why things work the way they do. The first few videos in this series are appropriate even for people who’ve never had calculus. Subsequent ones require you to remember just a few basic things that you learned when you took calculus.

If you never learned calculus before, or if you want a refresher on the details, the videos in this section are for you. We focus on the big picture, on understanding where each topic fits into the whole, and on being able to “see” why each concept is believable. So much of calculus is built on things you already know; we want to make sure that you see that.

Note: Unfortunately, the first few videos in this section haven’t been produced yet. You’ll have to know a few basics about derivatives in order to watch the first video listed below.
